By virtue of its own diversion effect, the cooling fan achieves the heat dissipation effect by realizing the "forced convection" heat dissipation method in a certain way. It has the characteristics of fast speed and good heat dissipation effect. However, many people will encounter a problem, that is, after a long period of time, the purchased cooling fan sometimes does not rotate, or it fluctuates slowly and quickly, and there are many reasons for this kind of failure, so what if the cooling fan does not rotate? What to do? The solution is as follows:

1. The cooling fan works under high temperature for a long time

Reason: There are many reasons why the cooling fan does not rotate. A broken fan is one type, and a problem with the power supply is also one. However, in general, the fan is not broken, because the cooling fan works under high temperature for a long time, which will easily cause the fan. The lubricating oil dries up.

Solution: You can use your hands to try to rotate it with external force-down, if there are signs of fretting or the rotation resistance is very large, it means that the fan is no problem, but the lubricating oil has dried up, you can remove the fan,-usually it is attached on the reverse side The self-adhesive sticker can be removed. At this time, you can see the fan shaft, add some oil or something, and turn it a few times with your hands. It feels that there is no resistance. Putting it back on should solve the problem.

2. The cooling fan rotates slowly, or even does not rotate

Reason: As a machine, it is difficult for us to fail. We did not choose to replace it immediately. We must find the reason from the faulty cooling fan. If the fan of the radiator stops rotating, it is probably a cause That is, the rotation speed of the cooling fan does not reach the normal speed required for the operation of the radiator I. In this way, if the cooling fan cannot reach its operating power, there will be the consequence of such a slow rotation or even no rotation, and the heat dissipation effect is definitely not as good as before.

Solution: We can try to adjust the fan blades so that its speed can meet the corresponding power requirements of the radiator. This time not only solves the problem, but also saves you the trouble of replacing a new device.

3. Do not pay attention to cleaning and maintenance

Reason: Because the environment where the cooling fan is located is relatively dusty, or it has been used for a long time, and we have not cleaned it, it is likely that the power supply of the cooling fan cannot rotate due to excessive dust. This is mainly due to More and more hot stars accumulate inside the cooling fan, resulting in poor heat dissipation inside the power supply, and unstable power supply, leading to its instability.

Solution: The machinery and equipment will have a certain lifespan during use. If you want to extend the lifespan, you must clean and maintain it regularly.
